TANK-HEATER.

Specification of Letters Patent. Patented Feb. 2t), 1917.

Application filed February 12, 1916. Serial N 0. 77,874.

To all whom it may concern: a

Be it known that I, RICHARD Loni), a citizen of the United States,residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented newand useful Improvements in-Tank-Heaters, of which the following is a specification.

This invention relates to tank heaters and consists in certain improvements in the construction thereof as will be'hereinafter fully described and pointed out in the claims.

The invention is particularly designed for use with tank heaters using lamps.

The invention is illustratedin the accompanying drawings as follows Figure 1 shows a plan view of the heater with the caps removed.

Fig. 2 a section on the line 2'2 in Fig. 8 a cap for the heater.

Fig. 4 a bottom view of the cap.

Fig. 5 an enlarged view of the reservoir and one of the lamps.

Fig. 6 an enlarged view of the 'draft tube insert.

1 marks the lamps. As shown there are three of these lamps. These lamps are connected by the pipes 2 with a common reser- Fig.1.

voir 3, the reservoir being arranged. at the. center of the group of lamps. A shell 4.- extends upwardly from the reservoir 3 andis supplied with a bail 5 at the top by means of which the lamps may be lowered into and lifted out of the heater.

The heater body 6 has a bottom 7, a cylin-. drical shell 8, a top plate 9, a central or "supporting tube 10 and entrance tubes 11. The: entrance tubes 11 are connected with. the

supporting tube 10 by the vertical slots 12 which extend downwardly to the chamber formed in the walls 8. The slots 12 are large enough to permit the'pipes Q'to pass through them. The lamps, therefore,.with the cen tral support formedbythe reservoir and its shell and the connecting pipes permit the introduction of the lamps downwardly through the tubes 11 and when the lamps reach the portion of the body within theshell' Sthey can be swung so as to bring the lamps under the plates 9. In this manner thelamps may openings and chimneys in the heater.

be readily removed and re-inserted into the heater without disturbing the body which is of considerable weight as it should be self sinking.

- Domes 13 are arranged in the plate 9 over the lamps and the chimneys 14 lead from the domes. The chimneys preferably have a bend or bends 15 to increasethe heating surface of the chimneys.

Amp 16 is provided so as to cover all the The which lift it slightly above the openings so that the draft is not interfered with. The cap 16 is preferably formed so as to cover all the openings and thus acts as a safety device as by reversing cap has the lugs 16 the cap and placing the lugs 16 upwardly the cap closes all the openings in theheater and immediately extinguishes the fire.

In order to more certainly separate the draft flowto and from the lamps and to prevent heating of the lamps and tank, I prefer to provide the deflecting plates 17 whichextend downwardly from the tube 10. To more thoroughly accomplish this purpose, I prefer to provide the draft tube insert 17, one of these being provided in each of the entrance tubes 11. The tube 17 is preferably formed of sheet metal and has a metal strip 17 b secured to one side of it. The metal strip has the extension 17 below the tube insert 17 lthus holding the tubeoff the bottom of the heater so as to allow the air to pass to the lamp near the bottom of the lamp. When the tube 17 is in place, as shown in Figs. 1 and 2, the strip 17 extends upwardly along the opening 12 thus bridging this opening. The end 17 of the strip is bent over v by'means of whichthe insert may be lifted. If it is desired simply to get access to the lamps for: trimming or attention the insert 17 may be lifted into'the tube 11 and held in thisupperfposition by aprojection 17 on so as to make a convenient handle the strip 17", the projectionbeing placed over i long enough to ex A supply tank "18 is arranged in the shell v 4:. It is somewhat smaller than the shell 4 so as to permit an air passage between the walls of the tank 18 and the shell t. The tank is closed at the top and has a valve plug 18 screwed into the bottom. A valve passage 19 extends through the plug and this is controlled by the valve 20. A'spring 21 is arranged on the stem of the valve 20, the stem having a head 22 at its bottom. Supporting lugs 23 are arranged on the plug 18 and hold the bottom of the supply tank OK the bottom of the reservoir. The height of these lugs determines the normal level of liquid in the reservoir.

Iniuse the supply tank is filled' in an in- 'verted position and then turned upright, the

V this position the valve would be lifted off its se'at'ilThis permits the down-flow of fuel from the tank so long as air can .pass into it to balance theair pressures. I prefer to make the bottomof the plug and the bottom of the pipe coincide because if there is a difference inthebottomilevel of the plug and the pipe aleakagethrough thejointbetweenthe plug 18fandthe bottom of'the' pipe may interfere withv the desired level in the reservoir.

T I Thefuel passes from the reservoir by way of the pipes 2 to the lamps. Each pipe 2 extends intoa valve boss 24; at the bottom of the reservoir. Passages 2 1 arearranged infthe boss and extendthe opening in the Ypipe into the reservoir. These openings are of a size to give when fully-open a proper maximum flow/to the lamps. In this way a'fiooding of the lamps is'prevented if the reservoir 'or-heater as a whole is slightly out of level.

a The valves 25 extendv into these bosses and control these passages 24, each passage 24 having a valve 25. The valve 25 has a stein 26 which extends to the top ofthe casing so that thelamp may be regulated, if desired, from the top.

It will be readily seen that these lamps Y may be readily removed-so as to adjust and v i yre,. t

lamp be su tableto produce a flame. .It will clean them. Preferably what is known as the blue. flame or wickless lamps are used as they 7 are somewhat shorter than most other lamps The form of these lamps is not important. 1 They may be of, the type usinga chiiiineyas gshown or of an open only requlrement being that the,

malso beobserYBd thatthe supply tank may 'be filled and replaced without the removal .offthe lampsandwithout turning out the I 7 taking care-.of :-the lamps mothe heater at different peripheral points on the heater so that by observing these with relation to the liquid in the tank 27 the user can readily observe whether the heater is level. This is quite important in that the lamps operate better and more uniformly where the heater is level.
